This appeal is from a conviction on three counts, which were violations of the Georgia Drug Abuse and Control Act, aggravated assault and simple assault. As the overruling of the general grounds of a motion for new trial were not argued, we limit our decision to the four enumerations which allege specific errors.

1. The first enumeration contends error in the court's explanation to the defendant as to his rights after his counsel had stated "the defendant wishes to make an unsworn statement." Appellant complains of the trial judge informing appellant in the jury's presence that "You may make an unsworn statement to the jury and no one can ask you any questions and no one can cross examine you." This was nothing more than a statement informing the defendant of his rights under the law of Georgia as it then existed. Such action has been ruled to be proper. Harris v. Stynchcombe, 227 Ga. 763 (2) (183 SE2d 205); Hunsinger v. State, 225 Ga. 426, 428 (8) (169 SE2d 286); Abrams v. State, 223 Ga. 216, 222 (5) (154 SE2d 443).

3. The remaining enumerations assert error in the court failing to instruct the jury on the provisions of Code Ann. 26-705 and 26-902.

As the testimony shows appellant was the aggressor, a charge of justification as a defense as contained in Code Ann. 26-902 was not necessary in the absence of a request. See Johnson v. State, 122 Ga. App. 542, 543 (2) (178 SE2d 42) and Howard v. State, 128 Ga. App. 807 (3) (198 SE2d 334). Furthermore, the court instructed the jury that in order for there to be a conviction for aggravated assault, the state was required to show that the shooting "was done not in self-defense or under circumstances of justification." (T. 160).

As to the other Code Section ( 26-705) which deals with acts done under a misapprehension of fact, the court did not err in failing to charge concerning a mistake of fact under the evidence presented below and in the absence of a written request.
